Helmet provided with a ring for connecting the helmet to an anti-theft system

Abstract

A helmet comprising a hard shell and a flexible shell extending inside the hard shell, the helmet including an attachment device suitable for attaching to an antitheft system external to the helmet. The attachment device comprises a ring suitable for having a link of said antitheft system external to the helmet pass therethrough, the ring being mechanically connected to the hard shell so as to be movable relative to the hard shell between a stowed position and an extended position; in the stowed position, a major portion of the ring is located inside a cavity that is defined at least in part by said hard shell and, in the extended position, at least a portion of the ring is located outside said cavity to enable said link of the antitheft system to pass through the ring.

1 . A helmet comprising a hard shell and a flexible shell extending inside the hard shell, the helmet including an attachment device suitable for attaching to an antitheft system external to the helmet, wherein the attachment device comprises a ring suitable for having a link of said antitheft system external to the helmet pass therethrough, the ring being mechanically connected to the hard shell so as to be movable relative to the hard shell between a stowed position and an extended position;
 in the stowed position, a major portion of the ring is located inside a cavity that is defined at least in part by said hard shell and, in the extended position, at least a portion of the ring is located outside said cavity to enable said link of the antitheft system to pass through the ring, the   wherein helmet includes a rigid base that is rigidly fastened against the hard shell, said ring being mechanically connected to the hard shell via the rigid base; and   wherein said base further includes guide surfaces for guiding movement of said ring relative to the base in order to guide the movement of the ring between the stowed position and the extended position, the guide surfaces being fixed in position relative to said hard shell and being located for the most part inside said cavity.

         4 . The helmet according to  claim 1 , wherein said base is rigidly fastened against the hard shell by a plurality of fastenings that are spaced apart from one another so that the base is pressed against the hard shell under the effect of the plurality of fastenings. 
     
     
         5 . The helmet according to  claim 4 , wherein a fastening of the plurality of fastenings is selected from the group of fastenings consisting in: a rivet, a screw, molding the hard shell over zones of the base, and combinations of these fastenings. 
     
     
         6 . The helmet according to  claim 1 , including a housing, the base belonging to the housing, the housing also including a cover preventing access to a mechanical connection zone between the ring and the base, in the stowed position, said major portion of the ring being located inside the housing. 
     
     
         7 . The helmet according to  claim 6 , wherein the ring is a rigid ring that is open and that, in any of said stowed and extended positions, is open solely to the inside of the housing. 
     
     
         8 . The helmet according to  claim 6 , wherein the ring is a rigid ring that is closed. 
     
     
         9 . The helmet according to  claim 6 , wherein the ring is flexible and is constituted by a cable having first and second terminal ends, which first and second terminal ends are attached to the base. 
     
     
         10 . The helmet according to  claim 9 , further including a locking device that is movable between a locked configuration and an unlocked configuration under the action of a control of the locking device, the locking device being fastened to the helmet, in the locked configuration, the second end of the cable is attached to the base via the locking device and, in the unlocked configuration, the second end of the cable is free and is located outside the housing. 
     
     
         11 . The helmet according to  claim 6 , wherein the housing contains at least one return member for returning the ring from its stowed position towards its extended position, said member being placed inside the housing and said return member belonging to a group of members comprising a resilient return member, and a magnetic return member. 
     
     
         12 . The helmet according to  claim 6 , wherein the housing includes two rails for guiding the ring to move in translation between the stowed position and the extended position. 
     
     
         13 . The helmet according to  claim 6 , wherein the housing includes at least one mechanical abutment arranged to be in contact against the ring when the ring is in its stowed position so as to prevent it from passing towards its extended position. 
     
     
         14 . The helmet according to  claim 6 , wherein the helmet also includes a manual actuation zone for actuating the ring and arranged to cause the ring to pass from its stowed position to its extended position in response to manual action exerted on the manual actuation zone. 
     
     
         15 . The helmet according to  claim 6 , also including an electronic device selected from the group of electronic devices constituted by:
 an antitheft alarm electronic device comprising a sound source and/or a transmitter for transmitting an alarm message via a wireless communications network;   an electronic device for geolocating the helmet;   a device for detecting an impact applied to the housing;   a device for detecting breaking of the ring;   a device for detecting tear-off forces applied to the housing;   an electronic detector device detecting at least one current position of the ring relative to the housing; and any combination of these electronic devices.
